Question

Please help. A rectangle has an area of 18cm

The lengths of the sides are whole numbers
How long could the sides of the rectangle be?

Answer 1

Hey mate!!!!

We know that area =

lxb

Here we should find the factors of 18.

Factors of 18 are

1, 2, 3, 6, 9, 18

Now the sides could be long as 18 itself.

Examples:

1 x b

1) 1 x 18

2) 2 × 9

3) 3 x 6

4) 9× 2

5) 18 x 1

6) 6 x 3

Hope it helps dear friend
